Which city is close to Boston?

I'm curious, could you please elaborate on which cities are situated in close proximity to Boston? I'm interested in understanding the geographical layout and potential commuting options from surrounding areas to the city of Boston. Are there any major metropolitan areas nearby that offer unique attractions or amenities that might complement a visit or relocation to Boston? Additionally, I'm wondering if there are any smaller towns or suburbs that are considered to be close-knit communities, offering a more relaxed lifestyle while still maintaining easy access to the amenities of Boston.
